The top-seeded players in the men's and women's singles draw have easily advanced at the U.S. Open Tennis Tournament in New York. But rain has forced the match between German Tommy Haas and Australian Lleyton Hewitt to be completed later Wednesday. Haas won the first set, 6-3, and the players will resume at 2-2 in the second set.

Martina Hingis, ranked number one in the world among the women, swept past young Daja Bedanova of the Czech Republic Tuesday, 6-2, 6-0. The victory puts the Swiss player into her sixth career semifinal at the U.S. Open. Hingis says she did not expect such an easy match on Tuesday. "I was actually surprised," she said. "The balls are actually coming at me in a slower pace. They were long and deep. But, still, I welcome this game with open arms."

Russian Yevgeny Kafelnikov reached the quarterfinal round with a 6-3, 6-4, 6-3 victory over Arnaud Clement of France. Kafelnikov says he was uncertain, coming into the match on Tuesday. "This morning I felt my chances were 50-50 I might lose and I might win," he said. "I was not that confident. But as the match was progressing, I felt like I was getting into my rhythm, the game I needed to play."

Serena Williams is in the semifinals after beating fellow American Lindsay Davenport, 6-3, 6-7, 7-5.
